摘　　要：针对传统制造业供应链管理信息不透明、数据流易窜改以及追溯能力不足等导致的供应链组织间缺乏信任、机会成本增加的问题,利用区块链技术设计了可信制造供应链溯源(trusted manufacturing supply chain traceability,TMSCT)框架。首先,设计了一种主从链协作机制,帮助用户在保护隐私的同时进行可信合作;其次,通过链上链下存储模式减轻分布式节点的存储压力;最后,基于布隆过滤器与Merkle树构建B-Merkle树,以快速判断当前区块是否包含目标数据。实验结果表明,B-Merkle树可以有效降低查询请求的平均处理时延,所提框架在数据存在性判断、隐私保护、灵活性和缓解节点存储压力方面相比现有解决方案具有更好的表现。To address the lack of transparency in traditional manufacturing supply chain management,the vulnerability to data tampering,and the insufficient traceability capabilities,which result in a lack of trust between supply chain organizations and increased opportunity costs,this paper designed the TMSCT framework by using blockchain technology.Firstly,it designed a master-slave chain collaboration mechanism to enable trustworthy collaboration while protecting privacy.Secondly,it implemented a hybrid on-chain and off-chain storage mode to alleviate storage pressure on distributed nodes.Finally,it constructed a B-Merkle tree based on Bloom filter and Merkle tree to quickly determine if the current block contained the target data.Experimental results demonstrate that the B-Merkle tree effectively reduces the average processing latency of query requests.The proposed framework outperforms existing solutions in terms of data existence verification,privacy protection,flexibility,and alleviating storage pressure on nodes.
